Lungs were designed by whom, or what?
Whatever you assume the causation was/is
They were very obviously designed to take in smoke, as this does occur in nature.
Inhaling sand occurs in nature too but I doubt that any rational person would constantly and intentionally inhale large volumes of sand. This is an indicator that most people have enough common sense not to do such a thing. If you did it would kill you. Take a look at what happened to people in the days of the dust bowl. They would more than likely perceive me as a lunatic if I was living back then and told them to go ahead and breath in the dust because dust is natural and that the act of inhaling it was natural. It all boils down to using common sense which may not be so "common".
All natural. "Disaster" is a judgment call.
Yes it is... To me, even one single person dying a self inflicted death is a disaster. But, I have empathy for other people, and so yes, when scores of people die from a self inflicted act, I view it as a disaster. At the very least, it is a tragedy.
The inability to survive under water is natural. Really only responding to your post cause you chose to emphasize natural. And because OP mentions this.
Yes, it is natural not to breath under water and this is my entire point. Common sense should cause people to know this fact. Same with vaping, or putting anything else into your body where common sense raises a red flag. You assume that vaping is natural and I think you are wrong.
Vaping is clearly natural. It occurs in nature.
Vaping is not "clearly" natural or anything else. Where are the facts, and evidence for that statement so that it can become "clear" to me? Sure, people breath in stream while cooking, breath in water in humid locations, etc.. but no where to my knowledge is there PG, VG, flavorings and nicotine all wrapped into one unit that is found in nature and inhaled, not to mention being inhaled for long periods of time. Once again, common sense throws up the red flag of caution. Breathing sand, lint, and other foreign particles is natural too but it becomes unnatural and a liability that flies in the face of common sense when intentionally consumed in unnatural ways or in large volumes.
then vaping is clearly natural as we were born with lungs that are clearly designed to allow vapor to be inhaled into them.
As stated above, it is natural for foreign substances in SMALL amounts. But, to intentionally subject the lungs too large amounts and for long periods of time is not found in nature.
One of these days, someone will have a rational argument for what is not natural.
I just provided a "rational" viewpoint ..... One of the components of common sense is rationality, which many people do not posses. Common sense eludes many people and instead they try to theorize away the things and events that are staring them directly in the face.
